Chapter 22 Configuring Bidirectional Forwarding Detection
Configuring BFD
Configuring IPv6 BFD Support for IPv6 BGP Neighbors
With Cisco MWR 2941 Release 3.5 and later, the Cisco MWR 2941 supports IPv6 Bidirectional
Forwarding Detection (BFD) configurations on SVI interfaces for IPv6 BGP neighbors.
Note Only non echo mode is supported for IPv6 BFD sessions.
This section contains the following information:
• Enabling IPv6 Support on the Cisco MWR 2941, page 22-4
• Configuring IPv6 BFD on an SVI Interface, page 22-5
• Configuring IPv6 BGP on the Cisco MWR 2941, page 22-7
Enabling IPv6 Support on the Cisco MWR 2941
To enable IPv6 support on the Cisco MWR 2941, complete the following steps:
Step 4
neighbor ip-address fall-over bfd
Example:
Router(config-router)# neighbor
ip-address fall-over bfd
Enables support for BFD failover.
Step 5
end
Example:
Router(config-router)# exit
Router#
Returns the router to privileged EXEC mode.
Step 6
show bfd neighbors [details]
show ip bgp neighbor
Use the following commands to verify the BFD configuration:
• show bfd neighbors [details] —Verifies that the BFD neighbor is
active and displays the routing protocols that BFD has registered.
• show ip bgp neighbor—Displays information about BGP and TCP
connections to neighbors.
